ABSTRACT:
A method of making a fiber having a single mode absorptive core whose position relative to the cross sectional plane of the inner multimode cladding varies along the length of the fiber. A groove or grooves are made in the outer cladding of the preform. When fiber is drawn from the grooved preform, the position of the core does not follow the centerline of the fiber; the position within the fiber varies in accordance with the grooves.
